Motivation and Background

Malaria is a severe and sometimes incurable disease triggered by a specific mosquito (Anopheles mosquitos) that infects humans by feeding on them. Although in the early 1950s malaria was eliminated from the United States of America, there have still been 1500-2000 reported cases of malaria every year. Malaria, worldwide though, is a more important issue; about 3.4 billion people live at a risk of malaria (usually third world countries with poor hygiene or travelers that come back from visiting these countries). The disease is a result of a type of microscopic parasite that is transferred thru mosquito bites, infecting red blood cells. [2] The transmission cycle of malaria is detailed in the figure below. Other ways people can catch malaria through exposure to infected blood are blood transfusions, sharing needles, pregnancy, etc. Certain population groups, including children, pregnant women, non-immune travelers, and people with HIV/AIDS, are more vulnerable to malaria, along with residents of third world countries. Lastly, high temperatures (above 20º C) are necessary to allow the mosquito to complete their growth cycle; as a result, malaria is prominently found in tropical, warmer areas. Malaria triggers high fevers, headaches, chills, fatigue, nausea, and other flu-like symptoms. [3]
